Re: Terminology ?

: : Is there a term(Name) for phrases like:
: : A pride of lions , pod of whales, muster of peacocks, flock
of birds, gaggle of geese etc etc?

: They are called "collective nouns".

Collective Noun also collective
A noun referring to a group of people, animals, or things, and occurring
in the singular with a singular or plural verb: army, audience,
couple, family, government, group. ... Collective nouns are sometimes
called group nouns and the collective label is sometimes applied
to plural-only words such as cattle, clothes, people, police, although
these are not collective nouns as such. There are many collectives
in popular and technical use for naming groups of people, animals,
or things. Some are familiar to most people, such as a bench of
magistrates, a flight of stairs, a flock of sheep, a swarm of bees;
others are less well known (and of uncertain provenance), such as
an exaltation of larks and an unkindness of ravens. ...
